How can we add more arguments to an existing query? Suppose I have in my theme
if (!$blog_query) $blog_query = $wp_query; while( $blog_query->have_posts() ) : $blog_query->the_post();
AND I want to add to the existing qurey two arguments before passing, say
'orderby' => 'post-title', 'order' => 'ASC',
How can I add these to the existing $blog_query ??
